Went off 3 times, Tires good. Then it went away rest of trip.

Took to dealer.

No faults recorded, cant find nothing.

Im a little miffed, I cant see getting a warning and nothing is recorded in the system.

 

Could easily be that you have a sensor in the wheel getting "tired". they do have batteries in then. I've been told they are good 5-6 years.

 

I should have added that if you are running Torque Pro, and displaying all 4 wheel's PSI, and have them trained to the correct location, you should be able to tell which wheel is giving you a headache. But if it were me, I'd replace all 4. If one goes bad, the rest are probably ready as well.

 

did you have a cell phone charger plugged into one of the 12v ports? Cell phone chargers have been know to cause havoc with the TPMS system. It is not a consistent problem but sporadic. Try changing the cell phone charger with another one.

Sorry, Torque Pro is just a OBD2 monitoring app that runs on an android device with a Bluetooth OBD2 adapter. Its not a replacement TPMS. What I was trying to explain was that if you were running that app on your smartphone, you would be able to see which wheel was acting up, but in reality, it is probably time to replace all the wheel sensors. they can be found on e-bay(but find OEM ones, not Chinese replacements) fairly inexpensively. the Tires need to be demounted, and the sensor is a part of the stem and are replaced from the backside of the rim(unfortunately).


Various websites suggest that the batteries in the sensors last about 5-7 years (Changing TPMS Sensor Batteries)

 

I get these all the time on my 2012. I'm running FORScan and it shows all 4 sensors working. Maybe is is the phone charger.
